GRAIN-DRILL.

SPECIFICATION forming part of Letters Patent No. 466,523, dated'Ja-nuary5, 1892.

Application filed March 11, 1891. Serial No. 384,689.

Be it known that we, PHILIP M. GUNDLACH and JOHN P. GUNDLAOH, citizensof the United States, residing at Belleville, in the county of St. Clairand State of Illinois, have invented certain new and useful Improvementsin Grain-Drills; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which'it appertains to make and use thesame.

The present invention has for its object to provide an improvedgrain-drill construction embodying the following novel and advantageousfeatures: first, an improved arrangement and location of parts wherebythe usual rectangular carrying-frame of the drill can be dispensed withand the seed-hopper attached directly to and supported by the axle,

While the tongue and the diagonal hounds or braces by which it isconnected to the axle afford a ready and convenient means for theattachment of the cross piece or rail to which the drag-bars of theseeding-fiukes are attached at points intermediate of its transverselength, so as to equalize the strain and avoid springing or bending ofthe cross-rail in use and in a vertically-ad j ustable manner, so as toregulate the drag of the fluke-points upon the ground and enable thesame to be adjusted to suit the degree of hardness of the ground metwith, its lowest adjustment being for very hard ground; second, apivotal attachment of the seed-hopper to the axle and connectingbracesextending forward from the hopper to the tongue-frame or hounds inorderto admit of a slight adjustment of the seed-hopper in a pivotal manner,so as to balance the drill and cause it to run easy, and which at thesame time constitutes a very'rigid and substantial attachment of theseedhopper in place; third, a simple and effective knuckle attachmentfor the lower end of the hand-rod by which the cross-rail of thedrag-bars is manipulated, so as to afford the proper leverage to saidrod in pushing down or pulling up the cross-rail from its respectiveupand down positions with the corresponding straight and zigzag positionof the seed-fiukes, the hand-rod being provided with a stop madeadjustable to suit the verticaladjustment of (No model.)

the cross-rail hangers above mentioned,which stop is adapted to engageagainst'a catch at- We attain such objects by the construction andarrangement of parts illustrated in the accompanying drawings, in which-Figure 1 is a perspective view of our improved drill complete; Fig. 2, adetail longitudinal section illustrating the cross-rail of thegrain-fiukes in its up position; Fig. 8, a similar View illustrating thesame in down or straight position; Fig. 4, a front elevation of thehand-rod for operating the cross-rail and its connected part-s; Fig. 5,a similar view of the catch for said rod or the body of the axle.

Similar letters of reference indicate like parts in the several views.

Referring to the drawings, 1 represents the axle of the drill, havingthe usual groundwheels and connected to the tongue 2 by means of thediagonal braces on hounds 3 and an upper cross-rail 4, as clearlyindicated in Fig. 1. In the present construction the rear end of thetongue 2 extends back only to the cross-.

rail 4, so as to leave a clear space back of said rail for the movementof the mechanism by which the fluke-rail is manipulated, as hereinafterdescribed.

5 is the seed-hopper, the end pieces or castings of which are formedwith pendent feet 6, that are pivotally connected by bolts with thebracket-pieces 7 on the axle.

8 are tie or connecting rodsextending from the seed-hopper to thetongue-frame and adjustably connected to the hopper in any suitablemanner, so that the hopper may have a limited pivotal movement impartedto it, so as to balance the-drill and make it run easy.

9 is the cross-rail, to which the drag-bars 10 of the grain or drillfiukes are connected in the usual manner, this cross-rail 9 beingjournaled to its supporting-brackets, so as to be capable of the usualpivotal movement from an up to a down position to draw the drillfiukesinto either a straight or zigzag line, in accordance with the nature ofthe ground.

. In the present invention the hangers ll'are connected tothe'cross-rail 9 at points intermediate of its length and are of aforked for- ICO mation to fit the diagonal braces or hounds 3, to whichthey are bolted in a vertically-adj ustable manner, preferably by meansof a cross-bolt passing through one of a series of holes or slots inboth the hanger and the hound, as indicated in Fig. 2. Any otherwell-known adjustment mechanism may, however, be used instead withoutdeparting from the spirit of this part of our invention.

The novel means by which the cross rail or bar 9 is moved into itsdiiferent positions, as

above described, consists of a hand-rod 12,

extending backward between the axle and the seed-hopper to within easyreach of the operator, its forward end being pivotally connected to abent lever 13,that is journaled to the back of the cross-rail 9 by ashoe 14, in which it has limited pivotal movement, as shown, itsconstruction being such that when the said rail is in its down positionsaid lever bears against the rail, as shown in Fig. 3, to aiford afulcrum for the pull or hand rod 12 in drawing the cross-rail into itsup position, and when the rail is in its up position the said lever willbear against its shoe 14 to afford a fulcrum for the hand-rod in forcingor pushing the cross-rail into its down position.

15 is a stop on the shank of the pull-rod 12,'

made adjustable by means of a wedge 16, so as to equalize or compensatefor the change in position due to the vertical adjustment of the hangers11 of the cross'rail.

17 is a catch-piece secured to the axle and provided with a projectingedge, against which the stop 15 engages to lock the parts in their upposition, and a loop formation 18, through which the hand or pull rod 12passes? catch-piece 17, attached to the axle, essenand is confined inproper position.

By our improved construction the drill-i frame can be of an exceedinglylight construe-l tion and still afford ample strength and stiifness ofparts, the different members of the present frame construction coactin gin a very perfect manner to stiffen and brace each other and at the sametime furnish a more the cross-rail 4, so as to leave a clear space atthe rear of the same for the movement of the fluke-setting mechanism,essenti. lly as herein set forth.

2. In a grain-drill, the combination of the axle 1, tongue 2, diagonalhounds 3, and crossrail 4 with the cross-rail 9 and the hangers 11secured to the hounds 3 and having pivotal connection with thecross-rail at points intermediate of its length, essentially as setforth.

In a grain-drill, the combination of the drill-frame, the hangers 11,secured thereto in a straight vertically-adjustable manner, and acrossor fluke rail 9, pivotally connected to the hangers, so as to be capableof a pivotal up-and-down movement to draw the drillflukes into astraight or zigzag line or rank, substantially as described.

4. In a grain-drill, the combination of the axle 1, tongue 2, diagonalhounds 3, andcrossrail at with the cross-rail 9 and the hangers 11,secured in a vertically-ad j ustable manner to the hounds 3 and havingpivotal connection with the cross-rail at points intermediate of itslength, essentially as set forth.

5. In a grain-drill, the combination of the cross-rail 9, pivotallyattached to the frame of the drill, with the hand or pull rod 12 andbent lever 13, attached to the back of said rail by a shoe 14, to becapable of a limited pivotal movement, essentially as set forth.

6. In a grain-drill, the combination of the cross-rail 9, pivotallyattached to the frame of the drill, with the bent lever 13, attached tothe back of said rail by a shoe 14, to becapable of limited pivotalmovement, the hand or pull rod 12, adjustable stop 15 thereon, and

tially as set forth.

7. In a grain-drill, the combination of the cross-rail 9, pivotallyattached to the frame of the drill, with the bent lever 13, attached tothe back of said rail by a shoe 14, to be capable of limited pivotalmovement, the hand or pull rod 12, the stop 15 thereon, and catchpiece17, attached to the axle and provided with a loop formation 18 forconfining the hand-rod 12 in place, essentially as set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
